STEAM-HEATING- COOKING-RANGE.

Specification of Letters Patent.

Application filed. November 18, 1914. Serial No. 872,808.

b 1/1! vi /tom it m my concern Be it known that I, ISAIAH P. TowLnn, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Steam-Heating Cookinglianges, of which the following is a specification.

This invention relates to stoves, and more particularly to a cooking stove which is provided with a suitable attachment for the generation of steam for heating a house during cold weather, and also for heating water for household uses, separate heating devices being provided for the generation of steam and the heating of the water, when it is desired to use them separately.

lVith the foregoing and other objects in view, this invention consists in such novel. features of construction, combination, and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing, which shows the improved stove and various connections for the conducting of the steam to various parts of the house and also the hot water retaining tank and heating means therefor also showing a part of the stove in section exposing the auxiliary water-heating mechanism and in describing the invention as illustrated in this drawing, similar reference characters will be used for reference to the various similar or corresponding parts of the invention.

Referring more particularly to the drawings, 1 designates the construction of the stove, which is preferably a cooking range having a fire-box 2 and side ovens 3 and 4. The upper surface 5 of the cooking range 1 has a boiler or water-retaining tank 6 mounted thereon immediately above the fire box 2 thereof, which tank has a water supply pipe 7 connected thereto. The water supply pipe 7 has a valve 8 mounted therein for controlling the supply of water within the tank. A water gage 9 and a steam gage 10 are associated with the boiler 6 so as to designate the amount of water and steam contained within the boiler.

A pipe 11 communicates with the upper end of the boiler 6 and is provided for the passage of steam which is enerated within the boiler 6 by a fire in the fire-box 2, having auxiliary communicating pipes 12, which pipes have communication with radiators (not shown.) throughout the houseor build ing in which the stove is located. Valves in control the passage of the steam through the various pipes.

The pipe 11 has a pipe 15 connected thereto, which pipe has connuunication with a water-retaining tank 16, which tank is positioned adjacent the stove 1 and is provided forretaining warm water for various household uses.

The pipe 17 also communicates with the tank 10 and with the lower portion of the boiler 13, and is provided for the passage of hot 'ater from the boiler into the tank 16, while the pipe 15 is provided for the passage of steam into the tank 16 for softening and keeping the water hot within the tank. A suitable stop-cock 18 is connected to the tank 16 to provide for the dispensing of water therefrom.

The stove 1 is provided with a compartment 20, which is positioned beneath the oven 3 and which compartment has a burner 21 positioned therein. The burner may be connected to a gas supply source or a gasolene tank, as is desired, and is provided for the purpose of heating the water in the tank 16 when it is desired not to use the entire stove or for the generation of steam. The compartment has a pipe 22 extending therein, which pipe has an enlargement 23 formed therein. The enlargement 23 is positioned directly above the burner 21 and it is provided for the retention of the water above the burner for the purpose of heating the same. The enlargement 23 has communication with the tank 16 through a pipe 24, which extends around the compartment and communicates with the tank 16.

In the operation of the improved stove as heretofore described; during the winter months or cold weather, when it is desired to heat the house in which the stove is mounted, the boiler (3 is filled with water and the fire is kept in the fire box 2 for the purpose of cooking, as well as for providing the necessary heat for heating the water within the boiler and for the generation of steam therein, which steam passes upwardly out through the supply pipe 11 and the auxiliary pipes 12 to various radiators (not shown) which are positioned within the various rooms of the house thus providing for the proper heating of the house. A certain amount of the steam passes downwardly through the pipe 15 and into the hot-Water tank 16, which steam will upon fusion with the water tend to soften the water as Well as keep the same heated. The boiler 6 has communication with the hot-water tank 16 through the pipe 17, so that any amount of hot water may be allowed to flow into the tank 16 from the boiler 6, the amount being regulated by the valve mechanism 19, which is formed in the pipe 17. During the warmer months, when it is desired not to heat the liouse, but it is desired to have hot water, the auxiliary burner 21 may be eniployed for the heating of the water within the tank 16.

In reducing the invention to practice certain ininor features of construction, combi nation and arrangement of parts may necessitate alterations to which the patentee is entitled, provided such. alterations are comprehended within the scope of what is claimed.

What is claimed is:

' In combination, a cooking range including a fire box and a compartment, of a steam boiler positioned upon the range and directly above the fire boX, means for supplying water to said boiler, a steam pipe connected to the upper end of the boiler for receiving steam therefrom, means for connecting the steam pipe to a plurality of radiators for heating a building, a water retaining tank located adjacent the range, a branch steam pipe connected to said steam pipe and to the tank for heating and softening the water therein, a pipe connected to the tank adjacent the bottom thereof and to the boiler adjacent its bottom to allow the water from the boiler to pass into the tank to aid in heating the water therein, and an auxiliary heater located in the compartment and operatively connected to the tank adjacent the bottom thereof to heat the water therein when not using the boiler.

In testimony whereof I affix my signature in presence of two witnesses.
